What is the rule for reloading steel mortars that are 6 inches or less?

The rule regarding the reloading of steel mortars that are 6 inches or less, according to NFPA 1123, states that there is no limit to the number of times they may be reloaded. This means that operators can load and fire these mortars repeatedly as long as they adhere to safety protocols and standards set out by NFPA guidelines. This flexibility allows for more extensive use of these devices during a fireworks display, provided that safety measures and proper procedures are followed.

In this context, steel mortars offer a certain level of robustness and structural integrity, which accommodates multiple reloads. However, it is crucial for operators to ensure that they inspect the mortars after each use and follow safety regulations to prevent any potential hazards during the display.

This understanding places emphasis on the importance of following guidelines and operating procedures to maintain safety while maximizing the potential of the equipment during fireworks events.
